Built for intensive workloads

This Adamant Custom tower pairs a 24-core Intel Core Ultra 9 285K with 128GB DDR5 and an Nvidia GeForce RTX 5090 32GB GPU. It targets professionals running rendering, modelling or AI learning tasks that demand sustained multi-threaded compute and large video memory. Windows 11 Pro 64-bit is pre-installed.

Graphics memory decides fit

The RTX 5090 brings 32GB of VRAM, the single figure that determines whether the system can hold your largest scenes, textures or model weights without paging to system RAM. If your workload fits inside that frame buffer the build will keep data on the fastest memory available.

Ready to expand storage and I/O

Two 4TB Samsung 990 PRO NVMe drives occupy two of the four M.2 slots, leaving two open for future capacity. Four SATA ports support the included 10TB HDD plus additional drives. Front panel USB 3.2 Gen 2x2 Type-C, rear USB4 Type-C and 2.5Gb Ethernet with Wi-Fi 7 give high-bandwidth paths for external arrays or network rendering.

Questions about this item

How does the 24-core Ultra 9 285K perform once installed in this tower?

The 24-core Intel Core Ultra 9 285K runs at a 3.7 GHz base clock and can boost up to 5.70 GHz, supported by a 360 mm liquid cooler and the Z890 EAGLE motherboard for sustained workloads.

What interface caps the dual 4 TB Samsung 990 PRO drives in practice?

Each drive connects through a PCIe 4.0 x4 M.2 slot on the Z890 EAGLE board, limiting sequential throughput to the drive-rated 7450 MB/s read and 6900 MB/s write.

What physical space and bays are needed to fit the 10 TB hard drive and liquid cooler?

The case provides two internal 3.5-inch bays for the 10 TB drive and a front-mounted 360 mm radiator for the liquid cooler within the 447 x 215 x 469 mm chassis.
